I'm not sure I'm following. Yes physicality is important but that's always been the case. As gifted as Henry was technically he wouldn't be the same if he had the burst of say Rice or Jesus even if they aren't slow themselves.the technical aspect will always win, and physicality always runs behind, The numbers Solanke Bowen Walkins and Palmer are well deserved. The best academies in the world are now in England, so we are going to see more and more English-educated players excelling. The process started 20 years ago, and now you see that England is a major export of quality players + the league is full of English players that will excel at most teams around the globe. It just comes with having the best league and the most income around, your academies improve.
Regarding the never-ending physicality vs. technicality debate... that was always the case. random example, Jonas Rodriguez, one of the worst footballers I have ever played with. He had a decent career, why? he was fast, strong, and relentless. 99% of technically gifted players I played with, now they have normal jobs.
It is what it is. We still have Ode, Mbappe, Gavi, Rodri. Football is still here, alive and with us. sit back and enjoy.
English academies have improved a lot but I don't think they're the best in the world, that's easily France imo. England has a golden generation atm but overall their youth teams aren't better run or set up than Spain Italy or Germany even.
